Influence of graphene oxide's characteristics on the fabrication and performance of crosslinked nanofiltration membranes

Graphene oxide (GO) is emerging as an excellent next generation material for water purification membranes. Its ability to be fabricated cost-effectively in large quantities and featured characteristics, such as hydrophilicity, makes it an equitable graphene alternative in respective nanometric appli...
